IMPROVEMENT lN APPARATUS FOR PUMPING FLUIDS FROM CASKS. &c.

Specification forming part of Letters Patent, No. 191,656, dated June 5, 1877 application filed May 4, 1877.

To all whom it may concern:

Be it known that I, WILLIAM F. OLAss, of Cleveland, in the county of Guyahoga and State of Ohio, have invented certain new and.

useful Improvements in Apparatus for Pumping Fluids from Oasks, &c.'; and I do hereby declare the following to be a full, clear, and

exact description of the invention, such as 'will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawings, which A of this specification, fully illustrate my invention.

A represents the bed or base-plate upon which the air-pump is supported' on suitable posts B B. The upper ends of these posts are formed with screws a, on which is first placed a flat ring or flange, b, then a leather or rubber disk, 0, and on that an inverted metallic dish or truncated cone, D, having a projecting flange around its lower edge to pass over the bolts a. On top of this flange is then placed a cylindrical air-chamber, E, having also a flange around its lower edge, and the whole then fastened by'nuts d screwed upon the ends of the screws at. These parts are further firmly united by any suitable number of bolts, 0, passing through them.

In the center of the flexible disk 0 is socured a metal plate, f, provided with a post, h, projecting downward from the center thereof. This post is hollow at its upper end, with a check-valve, It, on top, and a passage, 0', leading out at the side.

The lower end of the post it is bifurcated, and in the same is attached the inner end of a treadle, G, which is pivoted in a post attached to the under side of the flange b.

The flexible disk is distended downward to its full extent by means of an interior spring, H, interposed between it and the truncated cone D. In the top of this cone is a check-valve, m, to admit air into the air-chamber E, and to prevent the air from returning.

From one side of the air-chamber E extends a bent outlet-tube, I, to a check-valve, J, and to this check-valve is connected a rubber or other flexible tube, K, for conducting the air to the vent-plug that is to be inserted'in the cask or barrel, or other vessel, from which the fluid is to be pumped.

This vent-plug is constructed of a slightlytapering barrel, L, having near its upper end a suitable aperture for the insertion of a nipple, O, to which the end of the flexible tube K is attached.

The upper end of the barrel L has an interior enlarged chamber, a, and a suitable flange around its outer side. To this flange is bolted a cap, I, which has a central opening corre sponding with the main bore of the barrel. Between the barrel and the cap is fastened a rubber disk, 10, with a small central opening. This opening should be smaller than the outside circumference of a pipe, R, which is passed through the cap and barrel, and, of course, through the rubber disk, which latter formsa cutoff to prevent the escape of the air through the opening in the cap.

The cap P has also an interior chamber, n, corresponding somewhat with the chamber or within the barrel L. These chambers are, as seen, one above and one below the rubber disk 10, and are of great importance, as they allow room for the movement of the rubber disk in inserting and drawing out the pipe R, and thus facilitating such movement.

The plug thus constructed is driven into the vessel to be emptied, after which the tube R is forced down through the plug to any de sired depth of the cask or vessel to be drawn from. The air is now forced by means of the air-pump into the barrel L, and around the pipe B into the vessel, forcing the liquid up through said pipeR.

' The air-chamber E of the pump may be dispensed with, and the flexible pipe K attached directly to the check-valve m in the top of the cone D.

, Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. The combination of the truncated cone D with check-valve m, the flexible disk 0,

spring H, plate f, post h having passage 0' In testimony that I claim the foregoing I y, and valve k, and the treadle G, substantially have hereunto set my hand this 8th day of as and for the purposes herein set forth. January, 1877.
